Abstract (en)
[origin: WO0241414A1] The invention relates to a light emitting component comprising organic layers, in particular to an organic light emitting diode. The component consists of at least one doped charge carrier transport layer (2), a light emitting layer (4) and contact layers (1, 5) and is characterised in that a blocking layer (3; 3') consisting of an organic material is provided between the charge carrier transport layer (2, 2') and the light emitting layer (4). According to the invention, the energy levels of the charge carrier transport layer are chosen in such a way that efficient doping is possible and the blocking layer nevertheless ensures that non-radiating recombination processes on the interface with the emitting layer are prevented.
